To all whom z't may concern.'

Be it known that I, WILLIAM WoRoBEL citizen of the United States, andresident of Lansing, in the county of Ingham and State of'Michigan, haveinvented certain' new and useful Improvements in Screens, of which thefollowing is a specification.

This invention relates to window screens, and more particularly toscreens which may be rapidly and readily lifted or lowered at will.

The main object of my invention is to provide a window roll screen whichmay be rolled up in the manner of a window shade, and likewise lowered,thus eliminating the diliiculty of having to lift out screen frames, orhandle them in the manner of the lift window, as is the case withscreens at present in use. p

Another object of the invention is to pro-` vide a novel and practicallocking and releasing means for said screen, so that the same may besecurely and releasably held in an position in its fra`me.

'Ihe above and other objects will become a parent in the descriptionbelow, in which c aracters of reference refer to like-named parts in thedrawings.

Referring briefly to the drawings, F1 re 1 represents a frontelevational view o my device applied to a window, as viewed'from theexterior of the heuse, taken substantially on the line 3-3 of Fig. 5. p

Fig. 2 represents a side view taken substantially on the line 2-2 ofFig. 1.

Fig. 3 represents a front elevational view of my device applied to saidwindow and viewed from the interior of the house.

Fig. i is a longitudinal cross-sectional view of my screen in rolled-upposition, showing thev spring actuating mechanism.

Fig. 5 is a side elevational view take Referring now in detail to thedrawings,

the numeral l represents the window frame, and 2 the screen which isrolled upon a cyl-` inder 3 pivotally mounted to a shaft 6 rigid tosupports 4 secured to said frame. A

spring 7 .is coiled about saidl shaft and hasone end secured to saidshaft and the other to said cylinder, as shown.

A hood or cover 5 is provided pivoted at will to expose said rolled-upscreen, the cover in its lower position being provided for the purposeofconcealing Specication of Letters Patent. -Ptented Aug, 31, 1920,.Application' met neuember 29, 1919'. serial No. 348,153.

said rolled-up screen and to rotect the same.

The sides `o said screen 2 are` adapted to ride in runners 10a in thewindow frame, the inner sides of said runnerslbeing provided withserrations 10. A lower border 9 is attached to said screen by graspinwhich the his border l same may be pulled downward. is narrowed towardthe upper part as at 15, the space between the latter andthe formerbeing enlarged tol provide on each sid'e of the screen a hollow tube 20having an enlarged cylindrical chamber 15 on the inner side of saidtube. A rod 11 .passes through each tube20 and through the adjacentchamber'la, one -of said rods 11 being attached to alink 21, and the'other to a( bell crank`14 which has a handle portion 16. Ineach of thechambers 15a a spring 12 is coiled about the rod 11, and said rod 1sprovided with a stop4 in. the form of a nut 12a at its outer end, thatis, ofthe portion within the chamber 15a. The free ends of the rods 11are adapted to normally engage the serrations of the runners 10a, byforce of the coiled springs 12.

It is now apparent that, in order to lower the screen 7, the border orledge 9 is grasped in the hand and simply pulled downward. In order toraise the screen, the handle 16 is grasped and pulled in acounter-clockwise direction, thus disengaging the rods 11 from theserrations 10, whence the' force of the spring 7 causes the screen torise.

Having thus described my invention, what I claim and desire to secure by'Letters Patent, is as follows:

A roll screen comprising in combination a shaft supported on a windowframe, a drum rotatable about lsaid shaft, acoiled spring having one endattached to said drum and the other to said shaft, a screen adapted tobe rolled upon said drum, a hood for said drum and the screen thereon,hingedly mounted upon said frame, vertical runners in the sides of saidframes havingserrated interior surfaces, said runners adapted to guidesaid screenin its vertical movement, and releasable means for retainingsaid screen in `any desired position in said frame 'comprisinghorizontal tubular members at ed to engage said serrated surfaces, astop on each of said rods Within said chambers and coiled springs aboutsaid rods Within said chambers, a bell crank having one of said rodsattached thereto, a link having the other of said rods attached thereto,said link being also attached to said bell crank,

and a handle on the latter for actuating said rods.

Signed at Lansing, in the county of Ing- 10 ham and State of Mich., this20th day of Dec., A. D. 1919.
